I tried changing it back by clicking those options in tweak ui but unfortunately it my icons didnt came back. By the way these is in 16 bits colors. When im changing it to 32 bits all my icons are change back to windows xp's.

Oh my god that did the job. Hey thankyou you all so much for helping me out! I tried everything that i can do. I gave up actually and been thinking of re-installing windows. But hey after a month i visited this site again (i forgot that i wrote a thread for my problem here) and then viola!! Thankyou so so much guys! :grinthumb
